BACnet.Protocol.ObjectTypes.DateValue (bacstack v0.0.1)
View SourceThe Date Value object type defines a standardized object whose properties represent the externally visible characteristics of a named data value in a BACnet device. A BACnet device can use a Date Value object to make any kind of date data value accessible to other BACnet devices. The mechanisms by which the value is derived are not visible to the BACnet client. A Date Value object is used to represent a single day. In contrast, the Date Pattern Value object can be used to represent multiple recurring dates.

Types
@type common_object_opts() :: {:allow_unknown_properties, boolean()} | {:ignore_unknown_properties, boolean()} | {:revision, BACnet.Protocol.Constants.protocol_revision()}
Common object options for creation - all are optional.
allow_unknown_properties- Properties that are unknown to the object implementation are usually rejected. With this option, unknown properties (numeric identifiers usually means we dont know them) are accepted and put into a separate map. This does mean we can not validate or write them. Types of the values can be anything at this point. While you can read unknown properties with atom or integer as property identifier, you can only remove numeric unknown property identifiers from an object. Property identifiers of typeatomare only accepted, if it is a remote object (object implementation is only enforced if it is a local object). Numeric property identifiers are accepted regardless of remote object or not. For remote objects, this means you have to write "raw values" (usuallyEncodingstructs).ignore_unknown_properties- Properties that are unknown to the object implementation are usually rejected. With this option, unknown properties get ignored, as if they were not specified.revision- The BACnet protocol revision to check required properties against. Optional properties are regardless of revision available. SeeBACnet.Protocol.Constants.protocol_revision/0for the available revisions.
@type object_opts() :: common_object_opts()
Available object options.
@type property_name() ::

| :reliability

Available property names for this object.
@type property_update_error() :: {:error, {error :: atom(), property :: BACnet.Protocol.Constants.property_identifier()}}
The structure for property errors.
@type t() :: %BACnet.Protocol.ObjectTypes.DateValue{ _metadata: internal_metadata(), _unknown_properties: %{ optional(atom() | non_neg_integer()) => term() | BACnet.Protocol.ApplicationTags.Encoding.t() | [BACnet.Protocol.ApplicationTags.Encoding.t()] }, description: String.t() | nil, event_state: BACnet.Protocol.Constants.event_state() | nil, object_instance: non_neg_integer(), object_name: String.t(), out_of_service: boolean() | nil, present_value: BACnet.Protocol.BACnetDate.t(), priority_array: BACnet.Protocol.PriorityArray.t(BACnet.Protocol.BACnetDate.t()) | nil, profile_name: String.t() | nil, reliability: BACnet.Protocol.Constants.reliability() | nil, reliability_evaluation_inhibit: boolean() | nil, relinquish_default: BACnet.Protocol.BACnetDate.t() | nil, status_flags: BACnet.Protocol.StatusFlags.t() }
Represents a Date Value object. All keys should be treated as read-only,
all updates should go only through update_property/3.
Properties which are for Intrinsic Reporting are nil, if disabled. If Intrinsic Reporting is enabled on the object, then the properties can not be nil.
For commandable objects (objects with a priority array), the present value property is protected,
unless out of service is active. For the duration of out of service, updates to the present value
using update_property/3 are allowed. Once out of service is disabled, the present value is once
again protected from updates, as the present value is updated through the relinquish_default and
priority_array properties.
Functions
@spec add_property(t(), BACnet.Protocol.Constants.property_identifier(), term()) :: {:ok, t()} | property_update_error()
Adds an optional property to an object. Remote objects can not be mutated using this operation.
Please note that properties of services can not be dynamically added and instead
the object must be newly created using create/4.
@spec create( non_neg_integer(), String.t(), %{optional(property_name() | atom() | non_neg_integer()) => term()}, [object_opts() | internal_metadata()] ) :: {:ok, t()} | property_update_error()
Creates a new object struct with the defined properties. Optional properties are not
created when not given, only required, given and dependency properties are created.
Properties with a value of nil are ignored.
Only properties that are required for specific services (i.e. Intrinsic Reporting) are automatically created.
@spec get_all_properties() :: [BACnet.Protocol.Constants.property_identifier()]
Auto generated function to get the names of all properties this object supports.
@spec get_annotation(property_name()) :: [term()]
Auto generated function to get the annotations for the given property name.
@spec get_annotations() :: [{name :: property_name(), values :: [term()]}]
Auto generated function to get the list of annotations for each property.
@spec get_cov_properties() :: [BACnet.Protocol.Constants.property_identifier()]
Auto generated function to get the names of properties used for COV reporting.
@spec get_intrinsic_properties() :: [BACnet.Protocol.Constants.property_identifier()]
Auto generated function to get the names of intrinsic properties.
@spec get_object_identifier(t()) :: BACnet.Protocol.ObjectIdentifier.t()
Get the BACnet object identifier.
@spec get_optional_properties() :: [BACnet.Protocol.Constants.property_identifier()]
Auto generated function to get the names of optional properties.
@spec get_priority_value(t()) :: {priority :: 1..16, value :: BACnet.Protocol.BACnetDate.t()} | nil
Get the active priority value from the priority array, or nil.
@spec get_properties(t()) :: [BACnet.Protocol.Constants.property_identifier()]
Get the list of properties the object has.
@spec get_properties_type_map() :: map()
Auto generated function to get a map of property name to type.
@spec get_property( t(), BACnet.Protocol.Constants.property_identifier() | non_neg_integer() ) :: {:ok, term()} | property_update_error()
Get a property's value from an object.
@spec get_protected_properties() :: [BACnet.Protocol.Constants.property_identifier()]
Auto generated function to get the names of protected properties.
Protected is an annotation and the object modules prevent writing to this property directly in code. The protected properties are either written on creation or updated automatically depending on other properties being written to. Some properties are only written once at creation and never updated.
@spec get_readonly_properties() :: [BACnet.Protocol.Constants.property_identifier()]
Auto generated function to get the names of readonly properties.
Readonly is only an annotation that the property should be write protected
on the BACnet side, there is no actual write protection in the object.
This is a hint to the device server. If you need actual write protection, see protected.
@spec get_required_properties() :: [BACnet.Protocol.Constants.property_identifier()]
Auto generated function to get the names of required properties.
Checks whether the given object has a priority array.
@spec has_property?(t(), BACnet.Protocol.Constants.property_identifier()) :: boolean()
Checks if the given object has the given property.
See BACnet.Protocol.ObjectsUtility.has_property?/2 for implementation details.
@spec property_writable?(t(), BACnet.Protocol.Constants.property_identifier()) :: boolean()
Checks if the given property is writable.
Check BACnet.Protocol.ObjectsUtility.property_writable?/2 for a basic run-down.
@spec remove_property( t(), BACnet.Protocol.Constants.property_identifier() | non_neg_integer() ) :: {:ok, t()} | property_update_error()
Removes an optional property from an object. This function is idempotent. Remote objects can not be mutated using this operation.
Please note that properties of services can not be dynamically removed and instead
the object must be newly created using create/4. Required properties can not be removed.
@spec set_priority(t(), 1..16, BACnet.Protocol.BACnetDate.t() | nil) :: {:ok, t()} | property_update_error()
Sets the given priority in the priority array of an object. This function also updates the present value.
@spec supports_intrinsic() :: boolean()
Auto generated function to check whether the object type supports intrinsic reporting.
@spec update_property(t(), BACnet.Protocol.Constants.property_identifier(), term()) :: {:ok, t()} | property_update_error()
Updates a property of an object. To update the priority array, use set_priority/3 instead.
